Various embodiments of a system and method for adapting software elements based on mood state profiling are described. The system and method for adapting software elements may include a mood state component configured to, among other things, create a mood state profile of a user. The mood state profile may indicate characteristics of a user's mood state. The system and method for adapting software elements based on mood state profiling may also include a method of application development. The method of application development may include creating an application profile that indicates the mood-altering characteristics of the application. The application profile may be used to, among other things, determine modifications to the application during the application development phase. The mood state component may also enable applications to adapt to a user's mood state while the application is in use (e.g., at runtime).
